Text Via LAN
I have to build IP based wired alarm system. I have one master & 5 slaves.Master has 5 push buttons.
What I want to do is to use existing LAN infrastructure (cabling) & plug my devices to that network.when master press the button the corresponding slave device must turn on the alarm. Thats it.
Note: The existing LAN infrastructure is occupying PCs, Printers, Internet etc... I want to plug my devices to this network.
Is there any method to do this? PIC16F solution will be better...!! Any modules I can purchase as well.
